6. Molecular Solar Thermal Energy Storage System: Evaluation of Different Candidates
Sammanfattning : The development of solar energy can potentially meet the growing requirements for a global energy system beyond fossil fuels, however necessitates new scalable technologies for solar energy storage. One approach is the development of energy storage systems based on molecular photoswitches, so-called molecular solar thermal energy storage (MOST). LÄS MER
7. Hydro-Kinetic Energy Conversion : Resource and Technology
Sammanfattning : The kinetic energy present in tidal currents and other water courses has long been appreciated as a vast resource of renewable energy. The work presented in this doctoral thesis is devoted to both the characteristics of the hydro-kinetic resource and the technology for energy conversion. LÄS MER
8. Marine Current Energy Conversion
Sammanfattning : Marine currents, i.e. water currents in oceans and rivers, constitute a large renewable energy resource. This thesis presents research done on the subject of marine current energy conversion in a broad sense. LÄS MER
9. Electric Energy Conversion Systems : Wave Energy and Hydropower
Sammanfattning : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. LÄS MER
10. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building
Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
